Re: Fermatas with tremolos

[Simon Albrecht]

I think the best way to do it would be essentially an override to the 
beam, adding the fermata to its stencils. However I have to call on the 
expect Schemers around here (Harm, David N.?) for finishing it, since I 
haven’t been able to align the fermata to the horizontal center of the 
beam. This is where I got – output attached:

\version "2.19.80"

#(define (beam-with-fermata grob)
   (let* ((beam-stil (ly:beam::print grob))
          (beam-width (interval-length (ly:stencil-extent beam-stil Y))))
     (ly:stencil-combine-at-edge
      beam-stil
      Y
      UP
      (ly:stencil-translate-axis
       (ly:stencil-aligned-to
        (grob-interpret-markup grob (markup #:musicglyph 
"scripts.ufermata"))
        X
        0)
       (/ beam-width 2)
       X))))

{
  \repeat tremolo 16 { c'32 c''}
  \once\override Beam.stencil = #beam-with-fermata
  \repeat tremolo 16 { c'32 c''}
}

Best, Simon
